Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
Stack-based buffer overflow in the _assemble_line function in modules/pam_env/pam_env.c in Linux-PAM (aka pam) before 1.1.5 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a long string of white spaces at the beginning of the ~/.pam_environment file.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way the vhost kernel module handled descriptors that spanned multiple regions. A privileged guest user could use this flaw to crash the host or, potentially, escalate their privileges on the host. (CVE-2013-0311) It was found that the default SCSI command filter does not accommodate commands that overlap across device classes. A privileged guest user could potentially use this flaw to write arbitrary data to a LUN that is passed-through as read-only. (CVE-2012-4542) It was discovered that dnsmasq, when used in combination with certain libvirtd configurations, could incorrectly process network packets from network interfaces that were intended to be prohibited. A remote, unauthenticated attacker could exploit this flaw to cause a denial of service via DNS amplification attacks. (CVE-2012-3411) The CVE-2012-4542 issue was discovered by Paolo Bonzini of Red Hat. This updated package provides updated components that include fixes for several security issues. These issues had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2012-3955 (dhcp issue) CVE-2011-4355 (gdb issue) CVE-2012-4508, CVE-2013-0190, CVE-2013-0309, and CVE-2013-0310 (kernel issues) CVE-2012-5536 (openssh issue) CVE-2011-3148 and CVE-2011-3149 (pam issues) CVE-2013-0157 (util-linux-ng issue) This updated Red Hat Enterprise Virtualization Hypervisor package also fixes the following bugs : * Previously, the Administration Portal would always display the option to upgrade the Red Hat Enterprise Virtualization Hypervisor ISO regardless of whether or not the selected host was up-to-date. Now, the VDSM version compatibility is considered and the upgrade message only displays if there is an upgrade relevant to the host available. (BZ#853092) * An out of date version of libvirt was included in the Red Hat Enterprise Virtualization Hypervisor 6.4 package. As a result, virtual machines with supported CPU models were not being properly parsed by libvirt and failed to start. A more recent version of libvirt has been included in this updated hypervisor package. Virtual machines now start normally. (BZ#895078) As well, this update adds the following enhancement : * Hypervisor packages now take advantage of the installonlypkg function provided by yum. This allows for multiple versions of the hypervisor package to be installed on a system concurrently without making changes to the yum configuration as was previously required. (BZ#863579) This update includes the ovirt-node build from RHBA-2013:0556 : https://rhn.redhat.com/errata/RHBA-2013-0556.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues and adds this enhancement. last seen 2020-06-01 modified 2020-06-02 plugin id 78950 published 2014-11-08 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/78950 title RHEL 6 : rhev-hypervisor6 (RHSA-2013:0579) NASL family SuSE Local Security Checks NASL id SUSE_PAM-7815.NASL description The pam_env module is vulnerable to a stack overflow (CVE-2011-3148) and a DoS condition (CVE-2011-3149) when parsing users .pam_environment files.
